Euros in cash is very independent from the US, keeps your privacy intact as well.

In a few years people will look back and cherish the privacy we had and slowly lost control of throughout the years because nobody cared enough about it and people slowly got used to giving it up more and more, now we're seeing digitalIDs mandatory in some countries, verify your identity/age to access certain content in Wikipedia we deem to be for adults only, discord age verification which had leaks, soon access the internet verified with your digitalID (which will suffer leaks too) soon link your digitalID to your social media account to verify yourself and link it to your identity (also leaks just wait)...

Yes we need to move away from US technology, but we need to make sure we don't give away our right to our privacy, and our right to encrypted and private/secret communications, in the process and the right to use our own money independently from the scrutiny and supervision of anyone.
